Each DUO vase is a unrepeatable piece, chosen from a small pre-produced stock in a marble quarry. Since each marble block is unique, each piece appearance may vary from hundreds of possible natural designs and colours.With an unusual silhouette, the DUO vase highlights the vertical and tricks the human eye. The bi-materiality is aesthetically appealing, but also has functional reasons: mouth-blown glass cylinders can accommodate tall twigs and leaves, while heavy bases made of Portuguese marble like Pele de Tigre and Serpa assure astounding stability. The DUO vase is available in two sizes.
